citibanfin[.]com

The domain citibanfin.com was registered on June 03, 2026 through TuringSign Inc. d/b/a Cosmotown and is currently classified as a high‑risk generic phishing site. Its short age and immediate activation suggest a purposeful campaign aimed at credential theft.

Infrastructure analysis shows the domain resolves to the IPv4 address 198.251.84.200, which is hosted in Luxembourg and associated with FranTech Solutions. The web server returns an HTTP 302 redirect and presents a 401 Unauthorized title, while the TLS certificate is issued by Let’s Encrypt (YR1).

Open source threat feeds have recorded citibanfin.com in four AlienVault OTX pulses and the site appears on a single public blocklist. The Gridinsoft trust score of 28 out of 100 reflects a low reputation, and five of ninety‑five VirusTotal scanners flagged the host as malicious. PhishDestroy has already blocked the domain, confirming its active use in credential phishing.

The presence of a generic 401 Unauthorized page indicates that the malicious landing page may be dynamically generated or behind a login prompt, but the exact phishing lure has not been captured. Analysts should request samples of the HTTP payload and monitor for redirects to credential collection forms that mimic banking services.

Defenders should add citibanfin.com and its resolved IP 198.251.84.200 to network deny lists and monitor DNS queries for related look‑alike domains. Email gateways must enforce strict sender authentication and quarantine messages containing URLs that resolve to the identified IP. Continuous threat‑intel feeds should be consulted for any new indicators tied to this infrastructure.
